    direct clients to retry rather than failing permanently.
 *  New: Expose the framed protocol in `Connection`. Previously this would
    return the application-layer protocol (HTTP/1.1 or HTTP/1.0); now it always
    returns the wire-layer protocol (HTTP/2, SPDY/3.1, or HTTP/1.1).
 *  Fix: Permit the trusted CA root to be pinned by `CertificatePinner`.
